TO ALL WI-IOM IT MAY GONCERN:

I Be it known that I, HOMER H. STUART, of Jamaica, in the county ofQueens, and State of New York, havein'vented a certain new and usefulimprovement in instruments for measuring the ow of iiuids, commonlyknown as Gras or Water Meters; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the accompanying drawing making a part of thisspecification, and to the letters of reference marked thereon.

The object oi' my invention is to cause the rotation of a shaft or axlelby means of the iiow of a Huid, in such a manner that the quantitypassing through the instrument will be recorded by anr'ordinary counterconnected therewith.

To accomplish this purpose my invention consists in mounting upon anaxle, that is inclosed in a case connected with the pipe through whichpasses the fluid to be measured a series of vanes that are extended toreceive the-impulse of the iluidentering the case, and'remain extendedwhile impelled by the fluid' until it passes, from the c'ase, when theyare folded or retracted until, by the rotation of the axle, they areagain in succession presented to the action of the entering i'luidy Toenable others skilled in the art to which it appertains to make and usemy invention, I will proceedl to describe its construction and operationwith reference .to the drawing.-

Figure 1 is a section through the middle of a meter, represented as awater meter with the water passing through it inthe direction of thearrows; and

Figure 2 is a plan of the same. i

The vanes a 6 c d and e are hinged at their inner ends to a peculiarlyshaped hub or shaftf. The vane a opposite the receiving pipe is justopening to the impulse of the water; the vane 11 is fully'extended; thatat c having passed :the delivery pipe, is just beginning to be 4foldedtoward the shaft by coming in contact with the end of the circle y thatfills the lower portion 'of the case'; and the remaining vanes, Aal ande, are folded close against'the hub. The vanes are successively extendedon one side of the case toreceive the impulse of the water to rotate theaxle until they reach the delivery pipe, when they are folded towardsthe centre and are retained in a closed or collapsed position until theyagain reach the reception pipe, when they are" again successivelyreleased and opened by their respective springs, s. It will thus beseen, on reference to the drawing, that the difference between thesegments a: and y, included bythe vanes when extended and whencollapsed, indicates the amount of water delivered by the passage ofeach vane. I

Having thus described and illustrated the manner in which I prefer tomake the instrument, it may here be remarked that the vanes need not berestricted to the number shown, and they may be made curved andfurnished with pairing on their peripheries, and fitted with but-hingesextending along the angles of the hub, or otherwise, and the springsapplied in a different manner or omitted. The form of theI hub may alsobe varied without interfering with its function of sustaining thealternately extended and retracted vanes. The

counter, which is represented in tig. 2 applied to the side of theinstrument, may be' of any of the ordinary kinds that are suitable forthe purpose.

I claim as my invention, rotating the axle of a meter by vanes that arealternately extended and folded or retracted, substantially asdescribed.

And I also claim, by this invention, to measure a iuid body by passingit transversely through a cylinder, or other circular vessel, containingvanes revolving, in said cylinder or circular vessel, in such a mannerthat ythe said vanes, while moving in the direction of the owing body,are radii of la circle as large as the inner surface of the cylinder,and, while returning through the lower part of the cylinder to the`point where the fluid is received, they are folded or retracted so asto be the radii of a circle smaller than the periphery of the cylinder.
